A Fast Optimization Method for Level Set Segmentation
, 2009 Level set methods are a popular way to solve the image segmentation problem in computer image analysis. A contour is implicitly represented by the zero level of a signed distance function, and evolved according to a motion equation in order to minimize a

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Modeling of Two-Phase Flow in Rough-Walled Fracture Using Level Set Method
Geofluids, 2017 To describe accurately the flow characteristic of fracture scale displacements of immiscible fluids, an incompressible two-phase (crude oil and water) flow model incorporating interfacial forces and nonzero contact angles is developed.

A Variational Level Set Method for Topology Optimization Problems in Navier-Stokes Flow
IEEE Access, 2020 A novel algorithm for the topology optimization problem in fluid dynamics is presented, with the Navier-Stokes equations as state constraints, and the objective is to minimize the dissipated power of the fluid subject to a fluid volume constraint ...
